Is the Huawei Mate 40 Pro eSIM compatible?

Yes. The Huawei Mate 40 Pro (2020) supports eSIM in its UK version.

Verified against the manufacturer and UK carrier sources. Data last updated 2026-07-23.

The detail and the caveats

Nano-SIM plus eSIM; no Google Mobile Services.

Huawei pattern: The P40, P40 Pro and Mate 40 Pro (2020) support eSIM in UK models but ship without Google Mobile Services. The P40 Pro+ has no eSIM, and later Huawei flagships were not sold in the UK.

Dual eSIM: no, the Mate 40 Pro runs one active eSIM at a time (usually alongside the physical SIM).

Model level answers have limits, especially with grey imports and regional variants. To test the actual Mate 40 Pro in your hand:

  1. Open the dialler and dial *#06#.
  2. Look for an EID: a 32 digit number shown alongside the IMEI.
  3. EID present = the phone has eSIM hardware. No EID = no eSIM.

You can also check Settings > About phone for an EID entry.

A separate question

Is the Mate 40 Pro supported on the ONSIM network? No

Whether a phone has eSIM and whether it works on a specific network are different questions. The Huawei Mate 40 Pro is not on the ONSIM supported device list, so it will not work on the ONSIM network even if the handset itself supports eSIM. ONSIM is explicit that unlisted devices will not work and it is unable to troubleshoot them. A Virtual Landline (which diverts calls to the phone you already have, on any network) works with every phone.
